A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
A kind of test side for microphone electro mechanical parameter in product provided as shown in Figure 1 for one embodiment of the invention
Method, for anechoic room outside electroacoustical measurement end flow chart, include the following steps:
S11: basic parameter is determined according to test item in test instruction, test tone is generated by the basic parameter
Frequency and record command；
S12: the record command is sent to indoor agent side of eliminating the noise；
S13: the recording open state fed back in response to microphone in test product by the indoor agent side of eliminating the noise,
The testing audio is sent to indoor artificial mouth of eliminating the noise to play out；
S14: the recorded audio of microphone records in the test product of the indoor agent side feedback of eliminating the noise is received；
S15: parsing the actual parameter of the recorded audio, according to the actual parameter and the basic parameter, passes through
Track algorithm determines microphone electro mechanical parameter in the product.
In the present embodiment, this method can be mounted in electruacousticfidelity instrument or electric sound testing system.It is using
When the microphone of electruacousticfidelity instrument test product, tested product may be very poor without bluetooth or Bluetooth function module performance, but
Be most of product can all have usb debugging mouth (product usb debugging mouth be visible outside product, some product usb debugging
Mouthful be in interiors of products, it is externally invisible).
Since the electroacoustical measurement end of only a few can be by built-in interface come the order of call operation system, to pass through object
Reason connection, wireless AD B (Android Debug Bridge, Android debug bridge) directly control product.Even if can be with, realize nor
It is often difficult.In addition, since electric sound testing system is outside anechoic room, product in anechoic room, the two apart from several meters, physical connection
The problem of usb data line is too long to introduce excessive loss, lead to not communication.So by agent side as electroacoustical measurement end
With the transfer of test product.
Since test needs to carry out in anechoic chamber, so, electroacoustical measurement end is outside anechoic chamber, and test product is in anechoic chamber
Interior, the agent side as transfer is also in anechoic chamber.
For step S11, instructed in response to the test that tester assigns, the electroacoustical measurement end is according in described instruction
The project of test, to determine corresponding basic parameter.Corresponding testing audio is generated by the basic parameter, due to test
There are many kinds of the types of project, so, corresponding test item is determined in testing.For example, microphone is surveyed for the first time in product
In examination, it is necessary to all test each test item.At this point, the basic parameter of required determination is more, the test tone of generation
The frequency time is longer.After testing for the first time, such as, it is determined that part electro mechanical parameter passes through, and part is obstructed out-of-date, in product
After the adjustment of microphone corresponding site, for higher accuracy, the whole project of test can choose；It may be test effect
Rate only selects that the project not passed through in test for the first time is tested.In this way in test, tester can be according to reality
It needs to select corresponding test item, to control the time of test.While generating testing audio, it is also necessary to generate control
The record command of microphone in test product processed.
For step S12, the record command that will be determined in step S11, according to what is established in advance with agent side in anechoic room
Connection is sent to indoor agent side of eliminating the noise.
For step S13, the recording open state that the electroacoustical measurement end is fed back in response to agent side will be in step S11
The testing audio of middle generation is played out by the indoor artificial mouth of electric sound testing system control noise elimination.
For step S14, due in step s 12, record command being sent to test product, the wheat of test product
Gram wind is in recording state, and artificial mouth in step s 13 plays testing audio, the audio that microphone just plays artificial mouth into
Row is included, and determines recorded audio.After the completion of recording, Mike in the test product that agent side is fed back out of described anechoic room is received
The recorded audio that wind is recorded.
For step S15, the actual parameter of the recording audio is parsed, can be parsed by existing method, then
According to the actual parameter and basic parameter, by track algorithm, for example, harmonic track algorithm, to determine in the product
The electro mechanical parameter of microphone.
Can be seen that by the implementation method by using agent side is that electroacoustical measurement end and test product are established and connected
It connects, the transmission method of bluetooth is substituted.So that the microphone of electroacoustical measurement end and various test products can all establish connection, avoid
There is a problem of losing that data, delay is larger or delay is unstable during Bluetooth transmission, guarantee test result is accurate.
As an implementation, in the present embodiment, described that benchmark is determined according to test item in test instruction
Parameter, after basic parameter generation testing audio and record command, further includes:
Determine the first audio duration of the testing audio；
It is described to receive in the test product that indoor agent side is sent of eliminating the noise after the recorded audio of microphone records,
Further include:
The recording waveform for determining the recorded audio determines the second sound according to the waveform to the recorded audio cutting
Effective recorded audio of frequency duration, wherein the first audio duration is identical as the second audio duration.
In the present embodiment, since a part of blank audio during recording audio, may be recorded, so,
Cutting is carried out according to the waveform of recorded audio, with the effective recorded audio of determination, the testing audio needs and effective recorded audio
Isometric and frequency range is consistent, uses so that harmonic track algorithm calculates.
The principle of cutting is that waveform is consistent with the frequency sweep wave frequency range that artificial mouth plays over a frequency range.Allow to cut
For audio afterwards in starting there are the non-frequency sweep wave signal of certain time length, which is no more than " the record filling " of test macro setting
Time.Then the wave file cut is exported, the sample rate for exporting waveform needs to protect with the sample rate of electric sound testing system microphone
It holds consistent.
For example, electric sound testing system generate frequency sweep wave be it is known, from 8000Hz to 100Hz, duration is frequency
8.3s, the record filling time of setting are 100ms.The audio audio so cut is also 8000Hz to 100Hz, duration
8.35s allows to start the non-frequency sweep wave signal having no more than 100ms because the record of 100ms is filled.Electric sound testing system is adopted
Sample rate is 44100Hz, so the audio cut needs resampling to 44100Hz in export.
It can be seen that the duration by determining testing audio by the implementation method, when carrying out the effective recorded audio of cutting
It is long, it ensure that two inputs (testing audio and recorded audio) of track algorithm completely to it, to improve the accuracy of test.
As an implementation, in the present embodiment, the test instruction includes at least: detection frequency wave signal；
When test instruction includes at least detection frequency wave signal, the test item is included at least: frequency response, total
Harmonic distortion, phase.
It is described to be determined in the product after microphone electro mechanical parameter by track algorithm, further includes:
The electro mechanical parameter is detected, when the frequency is corresponding and/or total harmonic distortion and/or when phase parameter exception, until
Feedback radio reception channel assembly exception and/or radio reception passage length exception and/or audio include exception less.
In the present embodiment, microphone frequency response, phase, total harmonic distortion can pass through the humorous of electric sound testing system
Wave track algorithm acquires.After electro mechanical parameter has been determined, it can be used to evaluate whether microphone in product meets particular demands.
For all products (single microphone, microphone array) with microphone, the fluctuation of frequency response, total harmonic wave are lost
It very cannot be excessive.For example, the assembly of radio reception channel is not up to standard, radio reception channel is too long will lead to very big, the inexpensive wheat of frequency response fluctuation
Gram wind total harmonic distortion is bigger than normal, these can all destroy voice quality, influences the performance of Speech processing algorithm, reduces voice
Interactive experience, such as wake-up rate is low, recognition accuracy is poor.
For the product of microphone array, also require between each microphone the consistency of frequency response and phase difference one
Determine in range.If going beyond the scope, microphone array speech enhancement performance can decline, and can equally reduce the body of interactive voice
It tests, the problems such as wake-up rate is low, recognition accuracy is poor occurs.
It can be seen that according to determining electro mechanical parameter by the implementation method as reference, inquire the test product
There is exception in which configuration, thus, it determines where the test product needs to improve according to the parameter, is test product
Microphone prompts area for improvement.And then improve the effect of test.
